\[\boxed{\mathbf{440\ (}\mathbf{н}\mathbf{).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
Пояснение.
Решение.
\[1)\ \frac{7^{\backslash 2}}{18} + \frac{7^{\backslash 3}}{12} = \frac{14 + 21}{36} =\]
\[= \frac{35}{36} \Longrightarrow \frac{36}{35}\]
\[2)\ \frac{13^{\backslash 2}}{60} - \frac{7^{\backslash 3}}{40} = \frac{26 - 21}{120} =\]
\[= \frac{5}{120} = \frac{1}{24} \Longrightarrow 24\]
\[\boxed{\mathbf{440\ (}\mathbf{с}\mathbf{).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
Пояснение.
Решение.
\[1)\ 8\frac{3^{\backslash 3}}{4} - 7\frac{5^{\backslash 2}}{6} = 8\frac{9}{12} - 7\frac{10}{12} =\]
\[= 7\frac{21}{12} - 7\frac{10}{12} = \frac{11}{12} \Longrightarrow \frac{12}{11}\]
\[\boxed{\mathbf{440}.}\]
